ANGLE-COCK'.

Be it Aknownl that I, WESLEY WASHINGTON WIGGS, a citizen of the United States, resid-` ing at .N ashville, in the county of Davidson andState of Tennesseeliave invented certainnew and useful Improvements in Angle.

lthe fo lowing is. a specificarovements in My'invention pertains to im for train alrwhat are termed angle-cocks brake pipes. .A Said invention has for its Obj ect principally erwise interfering with the workmg or. operative position" of the cock or parts of the brake applysame ina simple, economic, and effective manner..-` v Said invention consists .of certain structural features, Substantially as hereinafter fully d'closed and -specifically pointed out bythe laims Inthe'accompanying drawings, Figure l is a sideV elevation of the-preferred embodiment Fig.'2.fis a vertical longitudinal section thereof produced through the section taken. through the stop-shoulder of .the Y angle-cock casing and the cock handleorle'ver superposed in position thereon with .its locking'mechanism. Fig. 4 is an enlarged detached .perspective of the cock-actuating handle or lever viewing the same from its attaching end. Fig. 5 is a cross-sectionproduced through said lever or handle and its containedlockingl or retaining means. Fig 6 is a disassembled perspective view of the slide with its articulated Or'pivoted bolt; and Fig. 7 isa like view showing the slide with its attached bolt and inclo'sing casing, parts of the latter beingbroken away;- and ligs. 8 and 9 are opposite side In. carryingout my invention" I providea suitable handle or 'lever Y1 for conveniently usual type or form'employed in fair-brake closing casing or shellS constituting a coupling'or connection between sections ofthe train-pipe cast or provided upon its upper which prescribe or restrict the arc of Inovefashion -ber 1b,

ment of said lever. or handle in operating saidv cock or valve. Said handle or lever, suitably adapted for application or attachment to thel Patented opt. 3o, 1906.

plug 2, being fitted thereto after the of a wrench, as well known and preferably pinned thereto, as at l, has a champreferably openingv out through the under side ofl said lever or handle andsuitably closed at the bottom by a removable cock or slide or closure 1X, and having the front end wall thereof formed with a forward eXtension or,stud 1 for engagement with the stops or abutments 3EL of the Vplug or cock casing 3 forY aidingn the limiting or prescribing move- I ment of said lever or handle.

Contained or housed within the chamber 1b of the handle or lever 1 is a supplementary casing or inclosure 4, having preferably upward and rearward inclined forward and rear ends and adapted itself toreceive or contain a sliding slide 5, having correspondingly-outlined end walls and equipped at its ends with guiding or controlling studs or extensions 5a 5b, respectively, receivedor fitting in openings or passages 4 4Min the end Walls of the supplementary inclosure or casing 4. Upon the stud extension 5b of. the slide 5 is arranged a spring 6 for delivering its tension or stress upon the slide, saidv spring extending `1n common with said stud extension through the opening4b 1n one en'd wall saidcasing 4 and bearin'g'upon the opposite end Wall of the .handle-chamber 1b, the purpose ofwhich is apparent. The opposite end stud extension 5a of the slide 5 has pivoted or articulated thereto a bolt 7 which is guided and works within a passage or aperture 1, produced through tne forward extension or stud 1c of the handle-chamber 1,` and which bolt is eiiective to be pro] ected Outward beyond said stud extension wnenthe tumbler' is key-actuated for engagement with either or two apertures or sockets 3b, formed in the cock-casing 3 close to the stops or abutnients 3, foreffectively locking the handle or lever 1 -in place from being tampered with or unauthorizedly manipulated, and therefore guarding against cuttingI Off the 1 air-pressure vor other pressure-supply from any one or more train-pipe sections, and accordingly from a IOO car or cars ofa train, the advantages of which are obvious. ably, with duplicate openings 5c 5, one being in outline just the reverse of the other, for the reception ofthe key-bit and ythe manipulation of the slide, together with :its bolt, from Opposite sides of the cock-actuating handle or lever, the object of Which from a Said slide is equipped, prefer-' point of convenience is apparent. Said keybit-receiving openings c 5d are practically of acorn shape or outline, as shown, for obvious purposes, the supplementary casmg also vaving correspon ing openings 4 4d .1n its opposlte sides registerin With the aforesaid openings, respectively, a so additional openings 4" in its opposite sides to receive and form bearings for the key beyond lits bit, as Well understood. The cock lever or handle 1 has also openings .1e 1f, produced .throughts p opposite sides 'ofthe key-rb it outline .and reg- -matic coverlng or lguar readily seen. v'From the aforesaid it 1s vbeistering in position with .the openings .in the supplementary casing. and |the.slideop enings to rovide for the insertion of the .key 'from eit er side-of thecockhandle or'leverandits engagement with and for actuat' theslide in rojecting .and withdrawing its olt, .as in loc ing and unlocking ,the lever or handle.

Thev key-openings *1e4 lf .are suitably. guard- .ed' by `pivoted spring-controlled escutcheon plates or guards 8 Ito provide .for the autQ- .lievedthat theoperation-ofthedevice will be clearly understood. lt is znoted, however,

'I thatl the contrivance .is .highly .eeotive for its ,intended purpose, .-being ,proof .against manipulation withoutlthe use ofits key,.and

- even :thought-thefcoek .leverior :handle retainmg vpin be removed Athe lever acould not be detached from the cock, -W- hich-.wouldzbe-nec- .essary to obtain tanneieotive grip or purchase upon thecock or plug for its actuation, since the bolt of .thelockjng .mechanism of .the lever or handle is stillgin .locked engagement with either of its .receiving-.sockets in the locking r'nechanism including a slide forfsaid bolt .housed Within 4said 4lever plug or cock casing.

1. A, device of thev character described, having :its actuating-.lever equiped with olt anda bolt'to project therethrou With-.a socket or notch in t e angle-cock cas- I and said lever provided -laterally with lkeyreceiving .means yto permit the. actuating of said slide and'bolt.

2. A device of the character described,

comprising an angle-cock-actuating lever equipped with a sllde for actuating a bolt adaptedto engage a socket in the angle-cock casing-or houslng and means for the effective retention of said'bolt in locked position.

3. A device -of the character described, comprising:anmngle-cocklever, .a `bolt effective to engagera socket in the.anglecookcas ing, a slideifor said=bolt duplicate keybit-receiving o enings .and vme ans adapted 4to retainsaid sli and bolt in looked position.

4. .A device lof .the .charactery described, comprising an angle-cock-operating [lever :having inclesed thereina. slide equip ed with .a bolt engaging .'a socket inthecoe -casing, andan inner or sup lementarycasing .containing said slide an .adapted to permit the .or Vaperture inzthehandle and throng .a for- War stud-.extension ofsaidihandle".
